Field Details

direction

             protected int direction
            

箭头的方向。可以是 SwingConstants.NORTH、SwingConstants.SOUTH、SwingConstants.EAST 或 SwingConstants.WEST 中的一个。

Constructor Details

BasicArrowButton

             public BasicArrowButton(int direction, Color background, Color shadow, Color darkShadow, Color highlight)
            

创建一个绘制指定方向和指定颜色箭头的 BasicArrowButton。

参数:

direction - 箭头的方向；可以是 SwingConstants.NORTH、SwingConstants.SOUTH、SwingConstants.EAST 或 SwingConstants.WEST 中的一个

background - 按钮的背景颜色

shadow - 阴影颜色

darkShadow - 深色阴影颜色

highlight - 高亮颜色

自版本:

1.4

BasicArrowButton

             public BasicArrowButton(int direction)
            

创建一个绘制指定方向箭头的 BasicArrowButton。

参数:

direction - 箭头的方向；可以是 SwingConstants.NORTH、SwingConstants.SOUTH、SwingConstants.EAST 或 SwingConstants.WEST 中的一个

Method Details

getDirection

             public int getDirection()
            

返回箭头的方向。

返回:

箭头的方向

setDirection

             public void setDirection(int direction)
            

设置箭头的方向。

参数:

direction - 箭头的方向；可以是 SwingConstants.NORTH、SwingConstants.SOUTH、SwingConstants.EAST 或 SwingConstants.WEST 中的一个

getPreferredSize

             public Dimension getPreferredSize()
            

返回 BasicArrowButton 的首选尺寸。

覆盖:

getPreferredSize 在类 JComponent 中

返回:

首选尺寸

参见:

• JComponent.setPreferredSize(java.awt.Dimension)
• ComponentUI

getMinimumSize

             public Dimension getMinimumSize()
            

返回 BasicArrowButton 的最小尺寸。

覆盖:

getMinimumSize 在类 JComponent 中

返回:

最小尺寸

参见:

• JComponent.setMinimumSize(java.awt.Dimension)
• ComponentUI

getMaximumSize

             public Dimension getMaximumSize()
            

返回 BasicArrowButton 的最大尺寸。

覆盖:

getMaximumSize 在类 JComponent 中

返回:

最大尺寸

参见:

• JComponent.setMaximumSize(java.awt.Dimension)
• ComponentUI

isFocusTraversable

             public boolean isFocusTraversable()
            

返回箭头按钮是否应该获得焦点。 BasicArrowButton 通常用作复合组件（如 JScrollBar 和 JComboBox）的子组件。由于复合组件通常会获得焦点，因此此方法被重写为返回 false。

覆盖:

isFocusTraversable 在类 Component 中

返回:

false

参见:

• Component.setFocusable(boolean)

paintTriangle

             public void paintTriangle(Graphics g, int x, int y, int size, int direction, boolean isEnabled)
            

绘制一个三角形。

参数:

g - 要绘制的 Graphics

x - x 坐标

y - y 坐标

size - 要绘制的三角形大小

direction - 绘制箭头的方向；可以是 SwingConstants.NORTH、SwingConstants.SOUTH、SwingConstants.EAST 或 SwingConstants.WEST 中的一个

isEnabled - 是否绘制启用的箭头
